问：石油粘度

丰田’s technical advice insofar as oil viscosity for the 2007 Avalon is as follows: "SAE 5W−30 is the best choice for good fuel economy and good starting in cold weather. If SAE 5W−30 is not available, SAE 10W−30 may be used. However, it should be replaced with SAE 5W−30 at the next oil change." Although 10W-30 oil is not recommended by Toyota that viscosity will not damage your engine. If you desire that this maintenance be performed by a certified Mechanic, dispatched by万博体育入口到您的位置，请要求机油/滤清器更换响应机械师将为您解决这一问题。如果您有其他疑问或疑虑，请随时重新接触万博体育入口。
